Description

The AMC8878/8879 series is a low noise, low dropout linear regulator operating from 2.5V to 6.5V input. An external capacitor can be connected to the bypass pin to lower the output noise level to 30VRMS.

Designed with a P-channel MOSFET output transistor, the AMC8878/8879 consume a low supply current, independent of the load current and dropout voltage. The internal thermal shut down circuit will limits the junction temperature to below 150°C. Other features include thermal protection, reverse battery protection and output current limit. Both AMC8878 and AMC8879 come in a miniature 5-pin SOT-23 package.
